IMPROVEMENT IN BACKS FOR VEHICLE-SEATS.

Specication forming part of Letters Patent No. 157,816, dated December 15, 1874; application iled October 30, 1874.

To all whom it may concern:

Be it known that I, MARTIN HALEPENNY,

' of Pontiac, in the county of Oakland and State ot' Michigan, have invented a new and Improved Spring-Back for Vehicles; and I do hereby declare the following to be a full and exact description of the same, reference being had to the accompanyin gdrawin gs forming part of this specification, in Which- Figure lis a perspective view of my invention; Fig. 2, a section showing the attachment of the slirings to the seat-rim, and Figs. 3 and 4, views showing modifications.

Similar letters of ret'erencein the accompanying drawings denote the same parts.

My invention relates to the spring attachments for the seats of vehicles termed lazybacks.7 These devices are usually composed of a wooden back-piece supported from the seat ot' a vehicle by springs, in such manner as to form a yielding back-rest for theoccupants. The object of my invention is to provide cheap, simple, and etl'ective means for attaching the springs to the lazy-back, and the seat or other support, in such manner as to obviate the welding of the springs to any of the parts employed. To this end the invention consists in the means employed for connecting the springs to the lazy-back and seat, which I will now proceed to describe and point out in the claims.

In the drawings, A represents the seat of the vehicle provided with a metallic rail, A', which extends around the back and ends, and is preferably turned up, as shown in Fig. 1, to form pivots B B, for the carriage-top, or as shown in Fig. 3, for the attachment of eye bolts O, to be hereinafter referred to. I) rcpresen ts theback-piece supported by the springs E E and F F, at a convenient height above the scat. The side or end springs E E are substantially horizontal at their front ends, and are curved upward at their rear ends, where they are riveted or otherwise attached to brackets G G, projecting from the backpiece D, the front ends being similarly atA tached to curved brackets H, rising from the rail A', as shown in Fig. l, or to the iiattened ends ofthe eyebolts O, as shown in Fig. 3. The back-springs F F are straight, and substantially vertical, extending from the rail A to the back of the piece D, to which they are screwed or bolted. The springs F and brackets H are attached to the rail Al by means of clip-plates I, which are so constructed as to it over one side of the rail, and meet the springs or brackets above and below the same, as shown in Figs. 1 and 2, the springs and brackets being attached to the plate I by screws or bolts t' t' passing through the ends of the plates.

From the foregoing it will be seen that the springs are connected to the other parts entirely by rivets or screws, instead of being welded.

By this arrangement the attachment can be readily removed, while the expense of the springs is .materially reduced, as the spring metal has only to be punched for the rivets or screws to be ready for application, and can be readily and cheaply replaced when brokeon. In case the rail Al is not employed, as in an open vehicle, the seat is provided with sockets S, adapted to receive the lower ends of the back-springs F, as shown in Fig. 4. The eyebolts O are adapted to turn on the pivots B, so as to accommodate themselves to the motion of the springs E.

I claim as my inventionl. The combination of the back-springs F and brackets H, with the rail A and clipplates I, substantially as and for the purpose specified.

2. The combination of the sockets S, applied to the seat and back-springs F, substantially as and for the purpose specified.
